Season four could see the passage of time moving even further but it’s not clear how much will have passed since the third outing.
While not much is known about Gaertner, he has been keeping fans up to date with shots from the set of Ozark season four which started filming in November 2020.
His Instagram bio reads: “Actor. I love stories that inspire & let me be a superhero.
“My motto: “ETC” Be Excellent, be True, be Cool. Jonah on @netflix ‘s @ozark.”
One snap showed him cutting his hair back to look more like Jonah with a before and after shot.
He shared the black-and-white photo with his 26,000 Instagram followers and captioned it: “Well, I had to let go of the Covid hair. But I must say, it’s good to be back!”
The star also posted a shot from his very first day filming on season one of the show, which featured his co-stars Bateman, Linney and Hublitz.
Ozark seasons 1 to 3 are streaming on Netflix now
